I've accidentally burnt my dimmer with a short. It is a common dimmer with a triac/diac/pot of the simplest configuration (the triac is a BTA16). After replacing the triac, this still does not work, and I'm almost sure the problem is the DB3 diac (breakdown voltage at 32 V). I have not this beast in my lab, so, I would like to know if it is possible to use two 32V zener diodes in series, back-to-back, to obtain approximately the same effect, a question that may be interesting for its own.- Here is a somewhat simplified schematic (snubber and some filtering cap not included)

Is it possible to use two zener diodes in series back to back to replace a diac?
